昆明金殿国家森林公园蝶类多样性季节性变化研究

于2010年10月至2011年9月对金殿国家森林公园不同季节蝶类群落的结构数量和多样性进行了调查研究。共采集蝶类标本972只,隶属9科,49属,69种。各季节蝶类属数、种数、个体数量、多样性指数以及均匀度指数大小均为:夏季＞春季＞秋季＞冬季;优势度指数为春季＞秋季＞夏季＞冬季。秋季和冬季之间的相似性系数最高,夏季和冬季蝶类相似性系数最低,这与季节之间的气候差异性相关。结果显示分布于昆明地区的多数蝶种世代数一年为2代或者2代以上。

Butterfly diversity dynamics in different seasons at the Jindian National Forest Park, Kunming, Yunnan

From October 2010 to September 2011, butterfly diversity was surveyed over four seasons at the Jindian National Forest Park, Kunming. Specimens of 972 butterflies, belonging to 9 families, 49 genera and 69 species were captured and identified. The butterfly genus, species, individual numbers, diversity index and evenness index in different season were analyzed. The results showed the priority ranking as summer＞spring＞autumn＞winter; The dominance index ranking had the trend spring＞autumn＞summer＞winter. The similarity coefficient was related to the different season’ climate and was highest between autumn and winter but was lowest between summer and winter. Many butterflies species have two or more generations each year in the Kunming area.
